Exactly this. I am a teacher, and I always tell my students “There is no such thing as a stupid question as long as it seeks to clarify, or to deepen one’s understanding. Any question posed with the sincere desire to better understand something is welcome.”
There are students who will ask questions because they weren’t attentively listening to my explanation (their peers always say something like “He just explained that”) — I will patiently explain it to them again while the rest of the class listens in (or tunes me out because the were listening and don’t need or want to hear it again.)
I want to encourage them to ask questions whenever and where ever they encounter things they do not understand; I hope that this mindset encourages them to do so whether be at school, at work, or in their personal relationships.
Always left front pocket; front right is for keys and such. I am also right-handed, but hold my phone and scroll with my left thumb, while I use my right hand for other touch-tasks on the screen. Always wondered if I was an outlier, too. (_)
